Right angle stud clamp



Aug. 24, 1965 w. G. EINSMANN RIGHT ANGLE swun CLAMP Filed May 9, 1963 INVENTOR. WILLIAM G. El/V-SMA/V/V BY K W xmm ATTORNEY United States Patent 0 3,262,417 RIGHT ANGLE STUD CLAMP William G. Einsrnann, 6325 Forest Ave., Ridgewood 27, N.Y. Filed May 9, 1963, der. No. 279,063 2 Ciaims. (61. 26997) The invention herein disclosed is a right angle form of clamp for enabling a carpenter to position a stud on the sill of a houseframe and to hold it in that position while being nailed.

Special objects of the invention are to provide a simple, practical form of holder which can be quickly clamped in place on a sill or the like, such as a sole plate or top plate and which can then be used to hold a stud in position where it belongs while being toe nailed to the sill or other member.

Toe nailing being the most secure form of fastening is generally preferred but this has a tendency, because of the angle at which the nail is driven, to cause the stud to drift off center or twist. The present invention overcomes this tendency and holds the stud solidly in place while being nailed.

Gther important objects of the invention are to provide this special clamp construction in a strong, durable, lightweight and inexpensive form, suitable for carpenters use.

Several of the clamps may be used to hold a member of studs in place, enabling a carpenter or amateur builder to construct walls, partitions and the like.

Preferably these clamps are made up in sufiicient size to hold different size stock material.

Other special objects and the novel features of construction, combination and arrangement of parts constituting the invention are set forth and will appear in the course of the following specification.

The drawing accompanying and forming part of the specification illustrates a present commercial embodiment of the invention. Structure, however, may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

FIG. 1 in the drawing is a side elevation of the clamp.

FIG. 2 is a front end view of the same looking in the direction of the arrow 2 in FIG. 1.

FIG. 3 is an opposite end view looking in the direction of the arrow 3 in FIG. 1.

FIG. 4 is a side view, showing the clamp applied to a sill and holding a stud in position for nailing.

The body of the clamp is shown as made up of a continuous length of steel channel having a back and side flanges, with the side flanges cut down at the center and the back bent at a right angle to form two rectilinearly related channels, one in horizontal position to fit over a sill and the other in vertical position to accommodate a stud to be nailed on that sill.

In the drawing the horizontal sill engaging channel is designated 7 and the upright stud receiving channel is designated 8, the first having a back 9 and side flange 1d, 11 and the second having a back 12 and side flange 13, 14.

This angular frame structure may be made up of relatively light sheet stock formed into channels as indicated, braced in this angular relation by lightweight, tubular braces 15 having flattened ends, riveted or otherwise secured at 16, 17 to the outer ends of the basks of the channels.

Adjustable clamps are provided for securing the horizontal base channel on the sill and for gripping and holding a stud in the upright channel.

did fili These clamps are shown as thumb screws 18, 19, threaded in the flanges 11 and 14, carrying swivelled abutments 2%, 21 or their inner ends and opposing pairs of spaced abutment 22 and 23 on the opposite side flanges 10 and 13, respectively.

These fixed abutments, as shown in FIGS. 1 and 2, are spaced to opposite sides of a center line of the companion clamp screw for effecting a secure three point engagement with the sill and stud and the clamp screws are located on centers closer to the backs 9 and 12 of the channels, as shown in FIGS. Z'and 3, so as to apply an otf center grip tending to crowd the clamp down over the sill and to crowd the stud the more firmly into the upright channel.

FIG. 4 shows the clamp in use for locating and holding a stud 24 in position on a sill 25.

In this view the clamp is solidly held in selected position on the sill by the clamp screw 18 and the stud 24 after being set in the upright channel is solidly held in proper position by the clamp screw 19.

In this relation the stud is held ready for toe nailing or other fastening, as indicated at 26.

While thumb screws have been found practical as a quick means of securing the clamp in place and securing the stud in the clamp, other forms of adjustable clamping means may be employed, such as cams, wedges or the like.

The side flanges 10, 13 are shown as having countersunk screw holes 27 between the spaced clamp abutments by which the clamp may be fastened on a bench or other support and similarly the back walls 9 and 12 are shown as having countersunk screw holes 28 for enabling the device to be mounted on a saw horse or other such support.

The clamp is strong and durable but light in weight and easily handled for the uses intended. It may be used with sole plates or top plates and in many places for building walls, partitions or the like. It can be used as a back-up clamp when toe nailing roof joists to top plate.

Further advantages are that it may be made up at low cost and that it requires no special skill or familiarity in its use.

This clamp may be used to hold but-t, miter, half lap, mitered and half lap joints at right angles while fastening these parts of work benches, doors, screens and the like. Full lap joints can be held for fastening by placing the same thickness of material in laps.

Also the clamp may be used to hold other materials, such as steel, aluminum, etc., while fastening at right angles with bolts, rivets, taping, welding or the like, if necessary, interposing asbestos or the like in the clamp when working with heat.

To aid in properly setting the clamp on the sill the channels may be provided with edges 29, 30, so that whichever of these is used as the upright channel this edge, corresponding to the center line of the stud, will show how the clamp need be shifted on the sill to line up with a stud center which has been marked on the sill.

For effecting a more positive grip the clamping elements may be knurled, pointed or similarly treated. The spaced clamping pads or abutments opposed to the clamp screws may be formed by dimpling inward the side flanges of the channels.

In setting up the studding, the clamp is placed over the sill in position with the marker 29 or 30 lined up with the mark 31 which has been made on the sill for that particular stud center. Then when the clamp screw of the horizontal channel is closed on the sill the device will be secured in place with the upright channel in position to hold a stud engaged in that channel lined up with its center over the center mark on the sill. Tightening of the clamp screw of the upper channel will then secure the Stud exactly centered over the sill and properly squared on the sill and firmly held for toe nailing the stud in its final position on the sill. I

After one side of the stud is toe nailed the clamp may be removed and secured in place at the other side of the stud, for toe nailing the stud at the opposite side, thus to provide a locking eflect positively holding the stud against external forces.

A number of the clamps may be used Where it is desired to hold a number of studs in place for nailing.

g The channels of the clamps may be made wide enough to be used with several different sizes of stock materials.

the other to receive a stud to stand on that sill at a right angle, and Y 7 adjustable clamps on said channels for securing the first mentioned channel over the sill of a building v 4 7 structure and for securing a stud within the second channel, u

said channels integrally united and consisting of a continuous steel channel made up of a back and side flanges with said side flanges cut down to the back 7 and the back bent at the point of cut into right angled relation and said clamping means mounted on said side flanges.

2. The invention according to claim 1 in which said 10 back and-side flanges of the channel have openings therein for screws or the like for securing the clamp on a bench, saw horse or the like.
